Description

Technical Field

[0001] The invention relates to the field of diamond micropowder pickling, in particular to a diamond micropowder pickling device. Background Art

[0002] Diamond micropowder is a new type of superhard and ultrafine abrasive formed by special processing of artificial diamond single crystals. The particle diameter is finer than 54 microns. Currently, there are single crystal diamond micropowder and polycrystalline diamond micropowder. Diamond micropowder and its products are widely used in automobile, machinery, electronics, aviation, petroleum, geology and other fields. With the continuous development of technology and products, the application field of diamond micropowder and its products is constantly expanding.

[0003] After the diamond powder is produced, it needs to be purified by the pickling process to remove impurities. In the pickling process, the diamond powder is put into a pickling barrel filled with a dilute sulfuric acid aqueous solution, and the dilute sulfuric acid aqueous solution is prepared in advance, and the concentration of dilute sulfuric acid is controlled between 8% and 10%. The diamond powder is soaked in the dilute sulfuric acid aqueous solution for 2-2.5 hours, then taken out and washed with clean water.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] Reference Figure 1-Figure 10 A diamond micro powder pickling device comprises a pickling barrel 1 which is erected on the ground through a support frame, a discharge port 2 is arranged at the lower end of the pickling barrel 1, and a water washing pool 3 is arranged below the discharge port 2;

[0040] The pickling barrel 1 is provided with an injection assembly, which is used for injecting pickling liquid, and the injection assembly includes a plurality of injection pipes 4 arranged on the inner wall of the pickling barrel 1, the upper and lower ends of the injection pipe 4 are open, and a plurality of injection holes 5 are provided on the surface of the injection pipe 4, and a vertical rod 6 is provided in the injection pipe 4, and the vertical rod 6 extends to the lower end of the injection pipe 4, and the lower end of the vertical rod 6 is fixedly connected to a blocking plate 7 for blocking the lower end of the injection pipe 4, and the upper end of the vertical rod 6 is fixedly connected to an injection pipe 8, and the injection pipe 8 is slidably connected to the upper end of the injection pipe 4;

[0041] The end cover 9 on the pickling barrel 1 is provided with a plurality of through holes adapted to the injection pipe 8, and the injection pipe 8 can move up and down along the through holes;

[0042] In this embodiment, a motor is provided on the end cover 9, and a stirring shaft 13 is fixedly connected to the output end of the motor, and the stirring shaft 13 extends into the pickling barrel 1;

[0043] The specific operation process of the pickling device is as follows:

[0044] The pickling liquid is injected into the injection pipe 8 through the liquid pump, and the injection pipe 8 is pushed downward. The injection pipe 8 moves downward along the through hole on the end cover 9, and the injection pipe 8 drives the blocking plate 7 to move downward through the vertical rod 6. At this time, the lower port of the injection pipe 4 is in an open state. At this time, the pickling liquid is mainly injected into the pickling barrel 1 from the lower port of the injection pipe 4. When the injection amount is one-third of the total amount of the pickling liquid, the injection pipe 8 is lifted, and the injection pipe 8 drives the blocking plate 7 to move upward through the vertical rod 6. The blocking plate 7 blocks the lower port of the injection pipe 4. At this time, the pickling liquid is discharged from the injection hole 5 on the injection pipe 4, and then diamond powder is added into the pickling barrel 1. The diamond powder falls into the pickling barrel 1 in the state of powder, and first contacts with the pickling liquid discharged from the injection hole 5 during the falling process, so that the diamond powder The surface of the diamond powder is fully in contact with the pickling liquid, and then falls into the pickling liquid in the pickling barrel 1. At this time, the amount of pickling liquid discharged from the spray hole 5 is one-third of the total amount of the pickling liquid. During the discharge of the pickling liquid from the spray hole 5, the diamond powder is also completely put into the pickling barrel 1. Then the injection pipe 8 is pushed downward, and the injection pipe 8 drives the blocking plate 7 to move downward through the vertical rod 6. At this time, the lower port of the injection pipe 4 is in an open state. At this time, the pickling liquid is still mainly injected into the pickling barrel 1 from the lower port of the injection pipe 4, and part of the pickling liquid is discharged from the injection hole. The injection amount is one-third of the total amount of the pickling liquid. At this time, when the pickling liquid is discharged, it impacts the mixed solution of the pickling liquid and diamond powder in the pickling barrel 1, further improving the mixing effect of the pickling liquid and diamond powder;

[0045] During the process of injecting the last one-third of the pickling liquid into the pickling barrel 1, the motor is driven to rotate, and the motor drives the stirring shaft 13 to rotate. At this time, the pickling barrel 1 has enough pickling liquid, and the fluidity is good, and the resistance to the stirring shaft 13 is small;

[0046] When designing the injection holes of the injection pipe 4, the directions in which the pickling liquid is discharged from the injection holes are designed to be in different directions, so that the pickling liquid discharged from the injection holes can cover the entire interior of the pickling barrel 1, and the total liquid level of the pickling liquid plus the diamond micro-powder in the pickling barrel 1 is located at the injection holes at the high point position, ensuring that the pickling liquid discharged from the injection holes at the high point position can impact and drop the diamond micro-powder adhering to the inner wall of the pickling barrel 1, so as to prevent the diamond micro-powder from adhering;

[0047] After the last one-third of the pickling liquid is injected, the motor is also stopped, and when the stirring shaft 13 stops rotating, the last pickling liquid discharged from the injection hole is sprayed onto the stirring shaft 13 to wash away the diamond powder adhering to the stirring shaft 13;

[0048] After soaking for 2-2.5 hours, open the discharge port 2 at the lower end of the pickling barrel 1, and the pickling liquid and diamond powder mixture in the pickling barrel 1 is discharged from the discharge port 2 and falls into the water washing tank 3, and rinsed with clean water. The pH value of the aqueous solution after rinsing reaches 7, ensuring that the residual pickling liquid is removed;

[0049] During the discharge of the mixed liquid from the discharge port 2, clean water is injected into the injection pipe 8, and the injection pipe 8 moves upward, and the lower port of the injection pipe 4 is blocked by the blocking plate 7, and the clean water is discharged from the injection hole, and the clean water washes away the diamond micro-powder adhered to the inner wall of the pickling barrel 1 and the surface of the stirring shaft 13. When the mixed liquid in the pickling barrel 1 is about to be discharged, the injection pipe 8 is moved downward, and the lower port of the injection pipe 4 is opened, and a large amount of clean water flows out from the lower port of the injection pipe 4, and the clean water washes the bottom of the pickling barrel 1 and performs the final cleaning of the pickling barrel 1. At the same time, the clean water can also play a role in cleaning the diamond micro-powder, that is, assisting the subsequent water washing tank 3 to rinse the diamond micro-powder with clean water. Clean water can be continuously injected from the injection pipe 8 to clean the water washing tank 3, and a water pipe can also be set at one end of the water washing tank 3, and the water pipe flows along the water washing tank 3 to wash the mixed liquid falling into the water washing tank 3;

[0050] In the design of the diamond powder pickling device in this embodiment, the injection pipe 8 cooperates with the injection pipe 4 to spray the pickling liquid to each part of the inner wall of the pickling barrel 1, and fully washes away the diamond powder to prevent the diamond powder from adhering to the inner wall of the pickling barrel 1 and failing to be pickled. At the same time, the pickling liquid discharged from the injection hole can impact and mix the diamond powder already put into the pickling barrel 1. Furthermore, in cooperation with the stirring shaft 13, the mixing of the diamond powder and the pickling liquid is accelerated, and the pickling liquid discharged from the injection hole can also wash away the diamond powder adhering to the surface of the stirring shaft 13, and prevent the diamond powder from adhering to the surface of the stirring shaft 13.

[0051] Reference Figure 1-Figure 10 The end cover 9 is provided with a ring body 10, and a plurality of arc-shaped slide grooves 11 are provided on the ring body 10. The injection pipes 8 are located in the slide grooves 11 one by one. A plurality of No. 1 wedge blocks 12 are provided on the upper surface of the ring body 10. A plurality of latch teeth 14 are provided on the inner ring of the ring body 10. The latch teeth 14 are meshed with gears 15, and the gears 15 can rub the latch teeth 14 to rotate;

[0052] A ring-shaped lifting plate 16 is provided above the ring body 10, and the lifting plate 16 is fixedly connected to the injection tube 8. A second wedge block 17 adapted to the first wedge block 12 is provided on the lower surface of the lifting plate 16, and when the ring body 10 rotates, the first wedge block 12 can squeeze the second wedge block 17 to push up the lifting plate 16;

[0053] In this embodiment, a servo motor for driving the gear 15 to rotate is also provided on the end cover 9, and the servo motor can drive the gear 15 to rotate forward and reverse; when the servo motor drives the motor to rotate forward, the gear 15 engages with the transmission gear 14 and drives the ring body 10 to rotate forward. When the ring body 10 rotates, the upper surface inclined surface of the No. 1 wedge block 12 presses the No. 2 wedge block 17 upward. At this time, the No. 2 wedge block 17 moves upward together with the lifting plate 16, and the lifting plate 16 drives all the injection pipes 8 to move downward, thereby achieving the purpose of the blocking plate 7 blocking the lower port of the injection pipe 4; when the servo motor drives the motor to reverse, the gear 15 engages with the transmission gear 1 4, and drives the ring body 10 to rotate in the opposite direction. When the ring body 10 rotates, the upper surface slope of the No. 1 wedge block 12 gradually falls off the No. 2 wedge block 17. At this time, the No. 2 wedge block 17, the lifting plate 16, the injection pipe 8 and the vertical rod 6 move downward under their own gravity, and the blocking plate 7 no longer blocks the lower port of the injection pipe 4; through the cooperation of the ring body 10 and the lifting plate 16, the execution of multiple injection pipes 8 is realized quickly and synchronously. When the pickling liquid is discharged from the injection hole, the diamond powder can be fully washed away. When the pickling liquid is discharged from the lower end of the concentrated injection pipe 4, the pickling liquid pushes the pickling liquid and the diamond powder in the pickling barrel 1 to stir and mix.

[0054] Reference Figure 1-Figure 10 The inner ring of the ring body 10 is also fixed with a cover plate 18, and the cover plate 18 is used to block the feed port 19 on the end cover 9;

[0055] When the ring body 10 rotates forward, the ring body 10 drives the cover plate 18 to rotate, the cover plate 18 is away from the feed port 19, the feed port 19 is opened, and diamond powder is put into the pickling barrel 1 through the feed port 19; when the ring body 10 rotates reversely, the ring body 10 drives the cover plate 18 to rotate and reset, and the cover plate 18 covers the feed port 19; the feed port 19 is opened for the input of diamond powder, and the feed port 19 is closed to seal the pickling barrel 1 to prevent foreign matter from falling into the body.

[0056] Reference Fig. 9 and Fig.10 The surface of the wedge block No. 1 12 is provided with a plurality of rotation grooves, and a ball 20 is arranged in the rotation groove;

[0057] A sphere 20 is disposed on the surface of the first wedge block 12 to convert the sliding friction between the first wedge block 12 and the second wedge block 17 into rolling friction between the sphere 20 and the second wedge block 17, thereby reducing friction resistance and improving the smoothness of the upward movement of the lifting plate 16.

[0058] A plurality of springs 21 are provided between the ring body 10 and the lifting plate 16. The springs 21 are sleeved on the injection tube 8. The upper ends of the springs 21 are fixedly connected to the lower surface of the lifting plate 16. The lower ends of the springs 21 pass through the slide groove 11 and are fixedly connected to the upper surface of the end cover 9.

[0059] The spring 21 is provided to pull the lifting plate 16 downward, so that the lifting plate 16 can drive the injection tube 8 to move downward quickly to prevent the injection tube 8 from being stuck in the injection tube 4.

[0060] Reference Figure 1-Figure 5 The water washing tank 3 includes an inclined portion 22 and a horizontal portion 23. A rectangular opening 24 is provided on the high end surface of the inclined portion 22. The rectangular opening 24 is opposite to the discharge port 2 of the pickling barrel 1. The lower end of the inclined portion 22 is connected to the horizontal portion 23.

[0061] The bottom plate of the horizontal part 23 is formed by fixing screens 25 of different grades, and a material trough 26 is provided below the horizontal part 23;

[0062] The aperture of the screen 25 is gradually reduced from the end of the horizontal portion 23 to the lower end of the inclined portion 22. When the mixed liquid flows into the washing tank 3 with the clean water, the clean water gradually pushes the diamond powder in the mixed liquid to flow. The diamond powder flows on the screens 25 with different apertures, and the diamond powder smaller than the aperture directly falls into the material trough 26 below, thereby realizing the particle classification of the diamond powder, that is, when the diamond powder is washed, the particle classification of the diamond powder is also realized;

[0063] As for the pH value of the aqueous solution after flushing, the length of the horizontal portion 23 can be extended so that when the pH value of the aqueous solution after flushing reaches 7, the diamond powder is discharged along the screen 25 to the material tank 26.

[0064] Reference Figure 1-Figure 5 The horizontal portion 23 is provided with a cylindrical stirring pool 27, a stirring plate 28 is rotatably connected in the stirring pool 27, a rotating shaft of the stirring plate 28 extends outside the stirring pool 27, and a driving motor 29 is fixedly connected;

[0065] The stirring tank 27 is located before the screen 25. The mixed liquid flows into the stirring tank 27 with the water flow. The driving motor 29 drives the stirring plate 28 to rotate. The mixed liquid and the water flow are fully stirred in the stirring tank 27, so that the mixed liquid is fully mixed with the water flow to ensure the uniformity of the pH value of the aqueous solution. Then, the mixed liquid flows into the screen 25 for grade screening. Figure 5 As shown, the stirring pool 27 is arranged at the lower end position close to the inclined portion 22. This state is one of the situations. The stirring pool 27 can also be arranged away from the lower end position of the inclined portion 22, as long as the pH value of the aqueous solution reaches 7 when the diamond micropowder aqueous solution flows through the screen 25.

[0066] Reference Figure 1-Figure 12The lower port of the pickling barrel 1 is reduced in diameter, and a horizontally fixed sleeve 30 is provided on the upper edge of the reduced diameter portion. The sleeve 30 has a radially arranged discharge hole 31. A swivel 32 is rotatably connected inside the sleeve 30. The swivel 32 has a radially arranged discharge hole 33. The discharge hole 33 coincides with the discharge hole 31. The material in the pickling barrel 1 falls into the inclined portion 22 along the discharge hole 31 and the discharge hole 33.

[0067] The sleeve 30 is provided to cooperate with the swivel 32, and the swivel 32 is rotated, so that the discharge hole 33 coincides with the discharge hole 31. At this time, the material in the pickling barrel 1, that is, the mixed liquid, falls into the inclined portion 22, as shown in FIG. Figure 8 and Fig.12 As shown, the rotating body 32 is in the shape of a round rod, and a strip-shaped discharge hole 33 is provided on it. When the mixed liquid falls along the discharge hole 33, it falls in a flat shape, which helps the mixed liquid to be quickly distributed in the inclined portion 22, accelerates the mixing of the mixed liquid and water, and dilutes the mixed liquid.

[0068] Reference Figure 1-Figure 12 The lower edge of the reduced diameter portion is rotatably connected with a cylinder 34, and a plurality of receiving grooves 35 are radially provided on the surface of the cylinder 34. The end of the cylinder 34 extends outside the pickling barrel 1 and is fixedly connected with a driven pulley 36, which is connected to a driving pulley 38 on the end of the rotating shaft through a belt 37;

[0069] A driving pulley 38 is provided on the rotating shaft of the stirring plate 28, and a driven pulley 36 is driven to rotate by a belt 37. The driven pulley 36 drives the cylinder 34 to rotate. When the receiving groove 35 on the cylinder 34 is opposite to the discharge hole 33, the mixed liquid falls into the receiving groove 35. Then the cylinder 34 rotates, and the receiving groove 35 containing the mixed liquid is rotated and tilted toward the rectangular opening 24. The mixed liquid can be poured into the water washing tank 3, so that the mixed liquid is intermittently put into the water washing tank 3, and the pressure of the water washing tank 3 to dilute the mixed liquid is reduced. As for the frequency of the mixed liquid being poured into the water washing tank 3, it can be determined by the diameters of the driven pulley 36 and the driving pulley 38. For example, by selecting a driving pulley 38 with a smaller diameter and a driven pulley 36 with a larger diameter, the rotation speed of the cylinder 34 can be reduced, thereby reducing the frequency of the mixed liquid being poured into the water washing tank 3 and reducing the pressure of the subsequent water washing tank 3 to dilute the mixed liquid.

[0070] Reference Figure 1-Figure 11 The support leg of the support frame is provided with an adjustment component for controlling the tension of the belt 37, and the adjustment component includes a sliding sleeve 39 fixed to the support leg by bolts, a compression spring 40 is fixed to one side of the upper end of the sliding sleeve 39, a compression rod 41 is fixed to the lower end of the compression spring 40, and an extrusion wheel 42 is rotatably connected to the pressure rod 41, and the extrusion wheel 42 presses on the upper surface of the belt 37;

[0071] After the belt 37 has been used for a period of time, the belt 37 will become loose, and slip will occur between the belt 37 and the driving pulley 38 and the driven pulley 36, making it difficult for the driving pulley 38 to drive the driven pulley 36 to rotate. For this reason, an adjustment component is provided to adjust the tension of the belt 37, loosen the bolts of the sleeve 39, move the sleeve 39 downward, increase the extrusion of the belt 37 by the extrusion wheel 42, increase the tension of the belt 37, ensure stable transmission between the driving pulley 38 and the driven pulley 36, thereby ensuring the smooth rotation of the cylinder 34 and extending the service life of the belt 37.

[0072] Reference Figure 1-Figure 5 , water supply pipes 43 are provided on both side walls of the water washing tank 3, and a plurality of nozzles 44 are provided on the water supply pipes 43, and the nozzles 44 penetrate into the water washing tank 3;

[0073] A nozzle 44 is arranged on the inner wall of the washing tank 3, and the water flow discharged from the nozzle 44 impacts the screen 25, washing the diamond powder blocking the screen 25 into the material trough 26, or washing the next level of gauze to avoid clogging the screen 25. At the same time, the water flow discharged from the nozzle 44 also plays a role in diluting the mixed liquid.

[0074] Working principle: The specific operation process of the pickling device is as follows:

[0075] The pickling liquid is injected into the injection pipe 8 through the liquid pump, and the injection pipe 8 is pushed downward. The injection pipe 8 moves downward along the through hole on the end cover 9, and the injection pipe 8 drives the blocking plate 7 to move downward through the vertical rod 6. At this time, the lower port of the injection pipe 4 is in an open state. At this time, the pickling liquid is mainly injected into the pickling barrel 1 from the lower port of the injection pipe 4. When the injection amount is one-third of the total amount of the pickling liquid, the injection pipe 8 is lifted, and the injection pipe 8 drives the blocking plate 7 to move upward through the vertical rod 6. The blocking plate 7 blocks the lower port of the injection pipe 4. At this time, the pickling liquid is discharged from the injection hole 5 on the injection pipe 4, and then diamond powder is added into the pickling barrel 1. The diamond powder falls into the pickling barrel 1 in the state of powder, and first contacts with the pickling liquid discharged from the injection hole 5 during the falling process, so that the diamond powder The surface of the diamond powder is fully in contact with the pickling liquid, and then falls into the pickling liquid in the pickling barrel 1. At this time, the amount of pickling liquid discharged from the spray hole 5 is one-third of the total amount of the pickling liquid. During the discharge of the pickling liquid from the spray hole 5, the diamond powder is also completely put into the pickling barrel 1. Then the injection pipe 8 is pushed downward, and the injection pipe 8 drives the blocking plate 7 to move downward through the vertical rod 6. At this time, the lower port of the injection pipe 4 is in an open state. At this time, the pickling liquid is still mainly injected into the pickling barrel 1 from the lower port of the injection pipe 4, and part of the pickling liquid is discharged from the injection hole. The injection amount is one-third of the total amount of the pickling liquid. At this time, when the pickling liquid is discharged, it impacts the mixed solution of the pickling liquid and diamond powder in the pickling barrel 1, further improving the mixing effect of the pickling liquid and diamond powder;

[0076] During the process of injecting the last one-third of the pickling liquid into the pickling barrel 1, the motor is driven to rotate, and the motor drives the stirring shaft 13 to rotate. At this time, the pickling barrel 1 has enough pickling liquid, and the fluidity is good, and the resistance to the stirring shaft 13 is small;

[0077] When designing the injection holes of the injection pipe 4, the directions in which the pickling liquid is discharged from the injection holes are designed to be in different directions, so that the pickling liquid discharged from the injection holes can cover the entire interior of the pickling barrel 1, and the total liquid level of the pickling liquid plus the diamond micro-powder in the pickling barrel 1 is located at the injection holes at the high point position, ensuring that the pickling liquid discharged from the injection holes at the high point position can impact and drop the diamond micro-powder adhering to the inner wall of the pickling barrel 1, so as to prevent the diamond micro-powder from adhering;

[0078] After the last one-third of the pickling liquid is injected, the motor is also stopped, and when the stirring shaft 13 stops rotating, the last pickling liquid discharged from the injection hole is sprayed onto the stirring shaft 13 to wash away the diamond powder adhering to the stirring shaft 13;

[0079] After soaking for 2-2.5 hours, open the discharge port 2 at the lower end of the pickling barrel 1, and the pickling liquid and diamond powder mixture in the pickling barrel 1 is discharged from the discharge port 2 and falls into the water washing tank 3, and rinsed with clean water. The pH value of the aqueous solution after rinsing reaches 7, ensuring that the residual pickling liquid is removed;

[0080] During the discharge of the mixed liquid from the discharge port 2, clean water is injected into the injection pipe 8, and the injection pipe 8 moves upward to block the lower port of the injection pipe 4 through the blocking plate 7, and the clean water is discharged from the injection hole, and the clean water washes away the diamond powder adhered to the inner wall of the pickling barrel 1 and the surface of the stirring shaft 13. When the mixed liquid in the pickling barrel 1 is about to be discharged, the injection pipe 8 is moved downward, the lower port of the injection pipe 4 is opened, and a large amount of clean water flows out from the lower port of the injection pipe 4, and the clean water washes the bottom of the pickling barrel 1 and performs the final cleaning of the pickling barrel 1. At the same time, the clean water can also play a role in cleaning the diamond powder, that is, assisting the subsequent water washing tank 3 to rinse the diamond powder with clean water. Clean water can be injected from the injection pipe 8 all the time to clean the water washing tank 3, and a water pipe can also be set at one end of the water washing tank 3. The water pipe flows along the water washing tank 3 to flush the mixed liquid falling into the water washing tank 3.
